4.2.1 Cyclic transmission processing
Cyclic transmission is performed using the LB/LW/LX/LY devices of the CC-Link IE
Controller Network board and the CC-Link IE Controller Network module.
The steps shown below are for the case of the link relay (B) on the personal computer
side.
1) B0 on the sending side (personal computer) turns on.
2) By a link refresh, the B0 information is stored in the refresh data storage area
(LB) of the CC-Link IE Controller Network board.
3) The B0 information in the refresh data storage area (LB) is stored in the link
data storage area (LB).
4) By a link scan, the B0 information in the link data storage area (LB) is stored in
a link device (LB) of the CC-Link IE Controller Network module on the
receiving side.
5) By a link refresh, the B0 information is stored in a device (B) of the CPU
module.
6) B0 of the receiving side CPU module turns on.
